Dynamic Location-Based Group Formation for Movable Incident Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dynamically creating location-based talkgroups for movable incident scenes often fail to include all relevant responding units, as they rely on statically defined distances, leading to inefficiencies in coordinating responses to moving incidents.
Innovation Solution
A method and apparatus that utilize a controller to dynamically form location-based groups by determining potential future locations of a movable incident scene based on its initial location, speed, and direction, and applying inclusion threshold rules to identify and include appropriate subscriber units, ensuring effective communication and coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If statically defined distances are used to form location-based groups, then the system complexity is reduced and ease of operation is improved, but the reliability of including all relevant responding units deteriorates
Solution Approach 1:
The patent transforms the static distance-based group formation into a dynamic system that calculates potential future locations of movable incident scenes. The controller dynamically adjusts which responding units are included in the group call based on predicted future positions, ensuring that all units that may be needed are included while maintaining operational simplicity through automated calculations.
2Device complexity
If statically defined distances are used for group formation, then the device complexity is reduced, but the productivity of coordinating responses to moving incidents deteriorates
Solution Approach 1:
The system performs preliminary calculations of potential future locations of movable incident scenes before actual response coordination is needed. By pre-determining which responding units should be included in the group call based on predicted trajectories, the system eliminates the need for complex real-time adjustments during incident response, thereby improving productivity without significantly increasing device complexity.

AI summary
Dynamic location-based group formation is provided for a movable incident scene (MIS) in a wireless radio communication system comprising a plurality of first subscriber units. A controller receives, from a requesting device, a request for a new group call for a MIS. The controller receives an initial location associated with the MIS and an indication of a speed and direction of travel of the MIS, and then determines one or more potential future locations of the MIS. The controller identifies a set of one or more inclusion threshold rules for each of the one or more potential future locations, and forms a location-based group including first subscriber units meeting at least one inclusion threshold rule for any one of the one or more potential future locations. The controller causes audio and/or data transmitted by the requesting device to be provided to the first subscriber units in the formed group.
